The episode is very similar to the episode 3.5 "The Surgery" from the series Saved By Bell. Both Tony and Zack are injured and are admitted to a hospital and learn that they both need surgery and have a nightmare were they died during the operation and attend their own funeral. There's a slight difference. In the Saved By the Bell episode: Zack attempts to escape from the hospital but is busted by Lisa's Mother and in this episode Tony's attempt from the hospital is successful.
